Subject: [PATCH v5 1/3] dt-bindings: pwm: tegra: Document Tegra234 pwm binding

Add compatible for nvidia,tegra234-pwm with nvidia,tegra194-pwm as a
fallback.
The PWM controller blocks are identical to ones found on the
Tegra194 SoC. No driver changes are required and compatible string
"nvidia,tegra194-pwm" will be used as a fallback.

Signed-off-by: Sandipan Patra <spatra@...dia.com>
---
V3 -> V4: Mention fallback compatible
V4 -> V5: Update Compatible with both Tegra234 and fallback
